I am Sang Choe, a final year CS PhD student in Language Technologies Institute at Carnegie Mellon University, advised by Eric Xing. I foreground practicality in my resarch and enjoy thinking across gradient-based optimization, data-centric AI, distributed ML systems, and ML tooling. Previously, I completed MS in Language Technologies at Carnegie Mellon University under the guidance of Jaime Carbonell. Before that, I earned BS in Electrical Computer Engineering & Mathematics (double major) from Seoul National University. I had also spent time as a research intern at Microsoft in 2021.
